SH-SY5Y cells, derived from a human neuroblastoma, were submitted to short- or long-term exposures to lithium carbonate concentrations ranging from 0.5 to 8 mM. Short-term exposures (4 days) to concentrations higher than 6 mM were found to reduce cell growth rate while exposure to 8 mM resulted in significant cell mortality. These ranges of concentrations(More)
Although local synthesis of 1,25D has been postulated to regulate parameters of cell growth and differentiation in non-renal cells, the physiological role of 1,25D production in bone cells remains unclear. We used the technique of RNA interference to inhibit the mRNA encoding the enzyme responsible for 1,25D synthesis, 25-hydroxyvitamin D 1alpha-hydroxylase(More)
BACKGROUND Plasma concentrations of sFlt-1, the soluble form of the vascular endothelial growth factor receptor (VEGF), markedly increase during coronary artery bypass graft (CABG) surgery with extracorporeal circulation (ECC). We investigated if plasma sFlt-1 values might be related to the occurrence of surgical complications after CABG. METHODS Plasma(More)
BACKGROUND This study was conducted to follow plasma concentrations of sFlt-1 and sKDR, two soluble forms of the vascular endothelial growth factor (VEGF) receptor in patients undergoing coronary artery bypass graft (CABG) surgery with extracorporeal circulation (ECC). METHODS Plasma samples were obtained before, during and after surgery in 15 patients(More)
Burkitt lymphoma (BL) features translocations linking c-myc to the immunoglobulin heavy chain (IgH) locus. By inserting a c-myc gene under the control of the 3'IgH locus control region (LCR) into the mouse genome, we generated c-myc-3'LCR mice that develop clonal BL or diffuse anaplastic lymphoma. We show in the present study that while BL from c-myc-3'LCR(More)
Several reports have demonstrated an important role of leukotriene B(4) (LTB(4)) in the immune system. We investigated whether leukemic blasts from acute myeloid leukemic (AML) and acute lymphoid leukemic (ALL) patients produced LTB(4), 12- and 15-hydroxyeicosatetraenoic acids (12-HETE and 15-HETE) and whether these compounds affected blast proliferation(More)
